Are these flush-free?

They are not. Tho we found the flush free ones don't actually work as well for holistic depression treatment. It probably depends what you need from B3. However the flush only lasted for a few weeks total. And each "flush" was about 30 minutes total. We actually ended up going with the 100mg no time release and taking them with meals because they did cause upset stomach.

I see two Rugbys here, one saying "timed release" and the other "extended release," which seem to be the same thing. Are they?

One is a capsule form and one is a captab form but the are the same thing

Did the packaging change? The coloring on the labels are different than the ones I ordered in the past

Yes, almost all Rugby and Major products have gotten updated packaging.

What is a captab? (How is it different from a capsule or a tablet in terms of ease of swallowing for the elderly?)

It has a tablet like composition in that it is not encased in gelatin but, it has a capsule shape so it’s easier to swallow.
